Telegram has a global search function. By tapping the magnifying glass icon in the app, you can type the exact username of a public group (preceded by an "@" or simply the name). However, due to the vast number of groups and Telegram’s prioritization of contacts, this method is less reliable. Many valuable communities are set to "private" and will not appear in search results, making the invite link the only viable route.
